Maxillary Swelling in an Infant

The following Case Challenge is provided in conjunction with the American Academy of Oral and Maxillofacial Pathology.

This case challenge presents a two-month old infant demonstrating upper lip asymmetry.

An asymptomatic swelling was noted in the area of the left anterior maxilla of this two-month old infant by the child’s parents. The swelling apparently was of rapid onset since the pediatrician at the one-month well baby check-up did not note it. The swelling caused an elevation of the left alae of the nose and slight facial asymmetry of the upper lip.

After you have finished reviewing the available diagnostic information, make the diagnosis.
